How about this?
$('#q681').css('display', 'none');
The Fieldxxx id values are the actual input/select/textarea parts of a field. And the (1) at the end of it just means the first checkbox input on the field. But the qxxx id values are the entire field and all of its parts (label, helptext, input, validation, etc.).
Since it sounds like you want the entire field hidden, instead of just the input, I think it'll work with the q id reference.
Also, many of us would recommend using classes instead of referencing the IDs directly whenever possible. In that case, you could add a class to the field (something like resident2SameAddressCheckbox) and then use Javascript to reference the class when hiding it:
$('.resident2SameAddressCheckbox').css('display', 'none');
